The test/survey takes a bit of time, but it's incredibly interesting at the end. It basically goes through and tells you how tolerant you are to certain 'disgusting' things (I'm talking disease, bees, perfectly healthy people, etc)....and then it also breaks down 'why' people are turned off by certain colored goo and such. You don't have to think much.....look at a picture and rate it....as simple as that. It's really interesting, so worth your 10-15 minutes if you're curious about this sort of thing.
